Seven people have appeared in two Northern Ireland courts facing serious charges including directing acts of terrorism after one of the biggest security operations involving MI5 and police against republican paramilitaries since the IRA’s 1994 ceasefire.

In one court case in Omagh it was claimed on Saturday that four alleged dissident republicans were linked to a terrorist training camp in County Tyrone.

A detective from the Police Service of Northern Ireland (PSNI) told the court there was evidence connecting the four accused to a secret firing range near Formil Wood in Tyrone.
